We have been split up for 3 years and usually his parents come to see him at Christmas, Easter and around his and the kids' birthdays and I arrange for the kids to be with him those weekends. They live four hours away and don't have much money. Thus far he has also always come to their birthday parties.
DD2 is 8 in 3 weeks. Her party has been booked for 2 months and her dad knows the date and had agreed to be there. We had also discussed what weekends he would have them around her birthday as we go on holiday the weekend after. He agreed to my suggestion which was that he just see her the day of her party as if she stayed over that night she would be hyper and he doesn't deal well with that. ( I also offered for him to see her the day after too or the evening of her birthday, which is a weekday, but he didn't want to.)
Anyway on the basis of that I arranged for my parents to see the kids on the day after her party.
Today I texted him to ask if his parents had discussed when they were coming down. He replied they were coming the day of the party so he wouldn't be helping and the kids could come the day after. I said we had made plans for that day following the previous conversation. I suggested he and his parents meet them at a pub for lunch halfway between us on the Saturday of the party but he said no, it was Sunday or nothing.
To add some context, he has Aspergers and hates his parents and often seems ambivalent about seeing the kids. In previous years I would have contacted his mum directly re arrangements but this time I didn't because it really shouldn't be down to me.
So now DD2 is upset Daddy won't be at her party and unless I mess my parents' plans around the girls won't see their paternal grandparents. And I will end up having to go to his hours after work one day to pick up her presents as he won't bring them over.
Basically whatever I do, I am the bad guy! Grrrr.
